Renewed July 18, 1938 6': Claims. (01. 1 78--92)' This invention relatesto a combined recording telegraph printer and perforator and moreparticularly to apparatus of this nature in which both the printing andperforating operations oc- 5 cur'on and in a single tape, respectively.

Commercial telegraph systems generally employ two general classes ofcircuits; trunk wire circuits and tie wire circuits. The trunk wiresextend between central oflices and are usually operated by a multiplechannel multiplex system- The tie wires terminate-in central ofllces andserve to connect branch oflices to the central office. A plurality ofbranch oflices may be connected to a central ofilce through one tiewire,

ingon the amount of traffic therefrom. In certain types of subscriberstelegraph services, of which the so-called -timed wire service is anexample, the subscriber will have one endof a tie wire terminating inhis oflice. Thus a subscribers office functions to transmit and receivetelegraphic communications similarto a branch officeand may beconsidered as such. Because of the expense, maintenance and attentionre-- quired to keep multiplex apparatus in operation,- the equipmentprovided to operate the tie wires is of the start-stop or simplex type.When it is desired to carry on telegraphic com-' munciations between twobranch ofllces'associated with the sanie central ofiice, it is entirelyfeasible to makedirect switchboard connection between their two tielines. However, ordinary the "branch oifices are located. in remotelyseparated localities so that they are associated with separate centraloffices. It is also entirely possible to repeat signals received at onecentral 'oflice from a simplex operated tie wire directly to a multiplexchannel of a trunk wire and extend the channel at the other centralofiice directly to another simplex tie wire.- Due to the slow speed ofoperation of the simplex systems as compared with multiplex operatedsystems, the above system of connecting does not efliciently utilize.the multiplex channel. Other objections to the above system are thatwhen a call is received in a central ofiice from a branch ofliceindicating a desire to communicate with a remote'branch oflice, acertain length of time is required to complete such necessary throughconnections during which time the transmitting branch oflice must'standidly by. If the'called branch ofllces tie,line is busy at this time, thecompletion of the through circuit inay be delayed for a substantialperiod and after connections are made, the rate of transmission over thestart-stop system may be the number of branch ofl'ices necessarilydependfar below the maximum speed of the multiplex channel. Moreover,'inorder that a multiplex channel will be immediately available for makingsuch through connections, it is necessary to provide a large number ofnormally idle multiplex '5 channels. 7

It has been found, therefore, that such messages can be handledexpediently and economically by providing signal storage devices at eachcentral oflice adaptedto receive signals from a 10 branch oflice tieline at any desired rate and from which the signals can be'subsequentlyretransmitted over the first available multiplex channel at the maximumspeed thereof. At the opposite central oflicE, these signals are againstored and 15 repeated over the second bramch ofiice's tie line, themultiplex circuit thus beingimmediately available for other service. Bythis arrangement the calling branch oflice immediately upon calling thecentral ofiice with which it is associated may 20 begin the transmissionof its message. Any short delays incident to the retransmission of suchmessages over the multiplex channel do not in any way inconvenience ordelay the calling branch ofllcex In addition to the signal storingdevice, it is necessary to employ'at each central office a telegraphprinter by which the calling branch oflice can communicate to thecentral oflice the identity of thecalled branch omce and by whichgeneral 30 telegraph business can be transacted. The printer is alsorequired for record and check purposes.

It is the present practice to employ at each central oflice means forrecording the signals on two separate tapes, one tape being in the formof a printed record, and the other in the form of a perforated tape.These recording means are necessarily of two general types, oneresponsive to signals of the start-stop variety and theother responsiveto signals of the multiplex variety.

In certain cases and especially when messages from a branch oflice arereceived with practically no intervening time intervals therebetween, itrequires considerable checking of the printed record against theperforated tape to insure that the perforated tape will be retransmittedthrough the proper transmitter. This same checking opera-- tion must beperformed at the secondcentral ofllce to insure that the messages areretransmitted over the correct'tie wire. Delays incident to thesechecking operations are very objectionable both from the standpoints ofeconomy and lost time. If the printed and perforated records bothoccurred on one tape,, it' would greatly 5 facilitate the handling ofsuch messages in the central omces.

It is therefore one of the objects of this invention to-provide amechanism by which signals 5 may be recorded in the form of a printedrecord and a. perforated record on and in a common tape, respectively,and in which both of said recordings register on the same transversesection of said tape.

Another object of this invention is the design 7 of the parts of acombined printer and perforator whereby such parts may be easily andcheaply manufactured and thus reduce the manufactur ing and maintenancecosts of the machine to a 15 minimum.

Still another object of this invention is to prostart-stop five unitcode'although it is to be understood that with modifications it may beadapted to operate in conjunction with other 25 codes without departingfrom the spirit of the invention.

As is well known to those versed in the art. this code is composed of astart impulse which is always of uniform line condition followed by fivea intervals of impulses of two different line conditions in variouscombinations thereof which in turn are followed by a stop impulse whichis always the same and of opposite line condition from that of the startimpulse.

code is thirty-two and in order to provide the requisite number ofselections to record letters, figures, punctuation marks, and printerfunctions, case grouping of signals is employed. Accord- 40 ingly, twocase shift signals are required, called a shift signal and an unshiftsignal. The purpose of the shift signal is to position the recorder sothat the following selections received will be properly recorded in thefigures group. The un-' 45 shift signal positions the recorder toproperly record signals in the letters group.

The selecting mechanism of this recorder comprises a single line magnetresponsive to line impulses cooperating with an independently rotat- 50able cam sleeve to variably and selectively position a set of primaryselecting elements in accordance with the received impulses. Theselection set up in the primary set of selectors is transferred in ashort interval of time to a second set of selectors 65 whereupon thefirst set is free to operate in response to a following signal codewhile the second set has nearly the entire interval of one signal tooperate the character selecting, printing and perforating mechanisms.

' 00,, The typewheel stop unit comprises a typewheel "shaft normallytending to rotate and a drum type stop unit for selectively stopping therotation of the typewheel shaft and typewheel.

The tape perforating mechanism comprises a 65 series of punch pins andelements adapted to be selectively interposed between said pins and arockable'member to selectively perforate the tape in accordance with thereceived code combinations of impulses. A tape feed mechanism coactingwith feed holes perforated in the tape,

intermittently feeds the tape through the machine. a

The structural part of the machine comprises a base plate upon which ismounted an upright 7 frame casting. The casting serves as journal ments.

The maximum. 35 number of selections available with the ,five unitpoints for the various shafts and as a support for mechanismsthatcomprise the machine.

Individual subcombinations of mechanisms that perform the relatedfunctions oi, the complete mechanism are so arranged that they may beeasily .and readily re'movedand interchangeably replaced when requiringrepairs or adjust- Thus the replacement of a complete recorder is notnecessary.

An electric motor secured to the base furnishes local power for'allselecting and recording operations through appropriate gearing andclutch mechanisms, the selector magnet having practically no work toperform, it acting -in response to the received impulses to only controlthe selection.

Referring first to Figs. 1, 2, 3 and 5, a base plat 2| has attached toit by screws 22, a main frame casting comprising mainly, two verticalplate sec.- tions 23 and 24 extending traversely of the machine andsuitable integral connecting members therefor. These vertical platemembers and their connecting members with various projection's'andsections of the main frame provide journal'and mounting points for thevarious mechanisms. The connecting members and sections of the mainframe will be given separate reference nu merals when referred tohereinafter in this specification. 4

Referring to Figs. 1, 2 and 3, the drive mechanism of the machine willnow be described. A group of four posts 25 (two only of which are shownin Fig. 2) attached to the base 2| has mounted thereon by screws 26 anelectric motor M. A pinion 21 secured to the motor shaft 28 meshes witha gear 29'. The gear 29 is secured to a flanged hub 3I- by screws 32,(Fig. 15) the hub 8| being attached by a'set screw 33 to an operatingcam shaft 34 for rotation therewith. The operating cam shaft 34 istr'aversely journaied in flanged bushings 35 and 38 which are held inplace by the bushing clamping members 31 and 38 respectively. Theclamping members 31 and 38 are attached toathe sections 33 and 4| ofthemain frame casting by screws 42 and 43 respectively. Fixed to the shaft34 by a set screw 44 is a flanged gear hub 45. A gear 48 is secured tothe hub 45 by screws 41 for rotation therewith and meshes with a gear48. The gear 48 is secured by screws 5| to a flanged gear hub 43, bestshown in Fig. 10, which in turn is secured by means of a pin 52 to acountershaft 53. The countershaft 53 is journaled in flanged bushings:54 and 55 which are held in the plate member 23 and in a section 58 ofthe main frame casting.

respectively, by bushing clamping members 51,

one of which is shown dotted in Fig. 15. Fixed 23. In mesh with theidler gear 83 is another idler gear 88 fixed to a hub 68 by means ofscrews II, the hub 63 being rotatably mounted on a stud I2 in the plateframemember 23. A typewheel shaft drive gear I3 meshes with the idlergear 88 and is driven therefrom. The typewheel shaft gear I3 and theselector cam shaft gear 64 serve to rotate their respective shafts in amanner that will be hereinafter described in connection with theirrespective mechanisms.

Selecting mechanism 2 and 18', is located in the bracket 11 and pivotally mounted on the rod 82 is a U-shaped armature lever 83. Anarmature 84 in operative relation with the selector magnet 14 is rigidlyattached to the pivoted end of the armature lever 83. The stroke of thearmature 84 and the armature lever 83 rigidly connected thereto islimited by the adjustment'of a stud 85 in the bracket ll Q and a flangedself-locking nut 88 thereon in operative relation with the armature 84.

A spring tension indicator lever 8'I (Figs. 2 and 3) pivotally mountedby a pin 88 in a left extension 88 of the selector mounting bracket 71has thereon ahorizontal projection 3| engaging with the upper end of anadjusting screw 82 carried by a horizontal projection 84 of the leftextension 88. A retractile spring 83 has one end attachedto the lever 81and the other end attached adjacent the left end of the armature"changing the positioniof the spring indicator ;lever 81 by means of theadjusting screw 32. By

changingthe adjustment of screw 82 the time.

when the magnet is energized. Also, the greater the tension on thespring 83 the quicker the armature 84 will be returned to its back stopwhen the selector magnet is deenergized. The etchings 35 oh theextension 88 of the bracket I'I serve to indicate the relative tensionof the spring 83.

As heretofore described, the gear 84 (Fig. 10) is continuously rotatingdue to the power communicated thereto from the continuously rotatingmotor M through the described gear train. The gear 64 is fixed by screws38 to a flanged hub 81 loosely mounted on a selector cam shaft 88.

The selector cam shaft 38 is traversely journalled in flanged bushings38 and IN which are held by bushing clamping members I83 and I84attached to the top of sections 23 and I82 of the main frame casting byscrews I85 and 188 respectively. The flange of the gear hub 31 carries aseries of three pins I81 (Figs. 18 and 11) equally spaced around theleft face thereof. These pins engageradial slots I88 in associatedBakelite seg ments I88. A groove on-the'outer edge of the segments I88has therein a circular coiled radially contractible spring I whichcauses the inner surfaces of the segments I83 to be frictionally engagedwith a sleeve 2 on a hub' H3. The hub H3 is fixed to the selector camshaft 88 by a set screw II4 for rotation therewith in abutting relationwith the left side of the gear hub 31. The right side of the gear hub 31is in abutting relation with the flanged bushing 38. It can be seen fromthe above description that, as the gear 54 and hub 81 rotate, theselector 'cam shaft 38 will tend to rotate therewith due to the actionof the segments I88 frictionally engaged with the of a nut I25 inthreaded engagement with the right end of the cam sleeve. A selector camshaft stop-arm III is also attached to the shaft 88 for rotationtherewith by means of a clamping screw II8 carried in said stop-arm. Aspacing collar II3 on the shaft 88 between the cam sleeve H5 and theflanged bushing 83 co-acting with the gear hub 81, keeps the shaft '38and the members carried thereby from longitudinal movement. A pointerpin I2I (Fig. 2) is located in the right end of the selector cam shaft38 for rotation therewith and a radial scale I22 is etched on thebushing-clamping member I84. This pointer I2I and thescale I22 inconjunction with the adjustment ofthe stop arm I H on the selector camshaft 88 determines the elapsed time between the release ofthe selectorcamshaft and the engagement of acam I23 with its associated se-- ditionsare also called marking and spacing in- I I. pulses. In the preferredembodiment of this ingized. The tension of the spring 83 is varied byventlon, the selecting magnet I4 is adapted to be rendered energized .bymarking impulses and rendered deenergized by spacing impulses. The

marking impulses are therefore intervals during which current istransmitted and the spacing impulses are intervals during which nocurrent is transmitted. The machine is so arranged that the startimpulse is spacing and the rest impulse marking.

It will be assumed that a marking impulse is (Fig. 10) is restrainedfrom rotation by the stop arm II1 rigidly secured thereto, the end ofwhich is engaged with a horizontal projection I26 on the armature lever83. This projection I26 is adapted to be interposed into the path of theend of the stop arm H1 when the armature and armature lever are placedin their marking position by the energization of the selector magnet 14.When the magnet 14 is deenergized, the spring 93 raises the armaturelever 83 and moves the projection I26 thereupon free from the end of thestop arm H1, whereupon the selector shaft is free to rotate.

Referring to Figs. 1, 2, 3 and 15, a selector unit mounting plate I21 issecured in a vertical position to bosses I36 in the front side of theplate section 23 of the main frame casting, by

screws I28. Studs I291: to I29, (Fig. 15) extend horizontally from thefront of the mounting plate I21 and have arranged thereon a plurality ofselector lever guide plates I3I and spacers I32 intermediate"therebetween. Between the six front guide plates I3l are' located flveselector levers indicated in general at I33 in Fig. 15, and individuallyby reference characters I33a to I'33e in Fig. 3. The spacers I32 areslightly thicker than the selector levers I33 and therefore the selectorlevers are movable between the guide plates I3I. The selector levers I33are not rigidly attached to the selecting unit or pivoted at any onepoint, but slide between the guide plates I3I. being restrained andguided in their movements by springs and guide pins. The springsattached to the selector levers are. indicated in general at I34 and I35in Fig. 15, and individually by reference characters I34a to I34e inFig.

3 (134a and I34e only being shown), and I35a tofl35e in Fig. 10. Thefixed ends of the springs I34 and I35 are attached to spring posts I36and I31 (Fig. 15) respectively, extending hori zontally from theselector unit mounting plate I21. The selector lever I33a is shown inits normal position in Fig. 15 with respect to its associated springsand guide memberswith the front guide plate I3I removed. The other fourselector levers I 33b to- I 33c are held in their normal position insubstantially the same manner-by their associated springs. The guideplates I3l and spacers [32 are clamped together by nuts position aspositioned by the rest impulse of the proceeding signal and that it isdesired to select another character; The electrical impulses thatcomprise the character code being received on the selector magnet in apredetermined arrangethe studs I29a to I29).- v

'of this impulse.

ment will be transformed-into mechanical selections of the selectorlevers I33 as will be hereinafter described. Assume that the characterto be selected is represented by a code combination composed of thefollowing flve intelligence impulses: spacing, marking, spacing,marking, and

marking. These impulses are preceded by a spacing start impulse and arefollowed by a marking stop impulse. The spacing start impulse, which isan interval of no current; renders the selector magnet 14 deenergizedand thus allows the spring 93 (Fig. 2) to rock the armature 84 andarmature lever 83 in a clockwise direction as seen in Fig. 2. The amountthat the spring 93 is allowed torock the armature lever is determined bythe position of the flange 85 on thestud 85. The flange 65' being solocated thatwhen the armature 84 comes in contact therewith, theprojection I26 (Fig. 10) extending from the side of the armature lever83 will be withdrawn from the path of the end of the stop arm II1.The'receipt of the start impulse on the selector magnet, therefore,disengages the projection I26, and the stop arm 1, whereupon theselector cam shaft 98 is free to rotate with the gear 64 through theaction of the heretofore'described friction clutch thereon. The speed ofrotation of the selector cam shaft 98 is so arranged relative to thespeed of transmission of the impulses that when the transmitting sourceis ready to transmit the first impulse, the cam shaft is revolved to theproper I26 thereon into the path of the end of the stop arm 1. At theend of a revolution of the selector cam shaft 98, the stop arm H1 andprojection I26 will engage and bring the selector cam shaft to a stopthereat in its normal rest position.

When the selecting magnet is associated with and receiving signals froma distributor transmitter, the selecting cam shaft 98 may be geared torotate a substantial amount faster than the transmitting shaft of theassociated distributor transmitter. In such case the selecting cam shaft98 will complete its revolution before the transmission of the completesignal. ference in speed, however, should be such that the marking restimpulse is being received on the selector magnet when the selector camshaft between the rotation of the selector cam shaft 98 and the speed oftransmission insures that the selector cam shaft will return to, and bestopped in its normal stop position before the The difcompletes itsrevolution. This difference in speed transmission of the start impulseof the following signal begins.

To return now to the five intelligence impulses that comprise thecharacter to be selected. The

start impulse which was spacing rendered the' selector magnetdeenergized, and as the first intelligence impulse is spacing, theselector magnet still remains deenergized for the duration During thefirst part of the time interval during which the first intelligenceimpulse is being transmitted and received on the selector magnet, thehigh part of the disccam I23a (Fig. 15) in operative relation with averselector cam shaft 68 continues to rotate, the

arm of the first selector lever I630 starts to en'- tical projection I69 on a rightwardiy extending gage said projection. .As the disc camI261; continues to rotate, the high part thereof will rock the selectorlever 533a in a clockwise direction high part of the disc cam I234;passes oi the projection 569 on the selector lever i83c and saidselector lever is rocked in a counter-clockwise direction back intoitsoriginal and normal position by the action of its attached springsItda and WM. 1

The second intelligence impulse of the code com-- bination is marking,and the reception of this impulse energizes the selector magnet I6 andtherefore the armature lever 83 is actuated into its marking position,as shown in Fig. 15. This brings the-cross-member I63 of the 'U- shapedarmature lever 86 into operative relation with rightwardly extendingprojectionsidd adjacent the top of the selectorlevers'itta to I33e.During the first part of the time interval during which the secondintelligence impulse is being received on the selector magnet, the highpart of the disc cam 923i) engages with the projection I 36 of theselector lever I331). This rocks the selector lever i332; in a clockwisedirection about the tip of its downwardly extending portion MI andbrings the projectioni44 of said selector lever in contact with thecross-member N3 of the arms,- ture lever 83. Thus the rotation of theselector lever i331: with the stud I62 serving as a. pivot is stoppedand as thecam i26b continues to rotate, the selector lever isrocked withthe end of the projection I64 thereof in contact'with the crossmemberIda acting as a pivot point. As selector lever i331 rocks with theprojection i4 3 acting as a pivot, the downwardly extending portion Idithereof slides to the left and off the square-shaped pivot stud M2,whereupon the springs I861) and I351: actuate the selector lever I861)downwardly into its selected position. A selector lever B36 is shown inits selected position by the dotted outline in Fig. 15. The downwardmovement of the selector lever is limited by pins I45 and 846, uponwhich arms of the selector lever rest with the lever in its rotation.-As the sleeve member I6I rotates in its selected position.

The third impulse of the signal code is spacing and the third selectorlever I33c will be left positioned in its normal position? in the samemanner as the first'sele'ctor lever was left positioned in its'normalposition. The-fourth and fifth impulses being marking, the fourth andfifth selector levers I 63d and .336 respectively will be actuated totheir selected position in the same manner as the second selector leverI861) was actuated to its selected position.

From the above paragraphs it is evident that.

the reception of spacing impulses on the selector inag net aretransferred to and represented by their respective selector levers beingin their un-- selected or normal position. The marking impulses aretransferred to and represented by their respective selector levers'beingin their selected position. Hereinafter the unselected and selected'positions of the selector levers will be referred to as spacing andmarking positions respectively of said selector levers. r I I Ata-predetermined point in the revolution. of

the-selector cam shaft98, a'high part of the cam I The purpose of thetrip lever I231 engages the top-right end of a substantially T-shapedlever I41, the left end of which is pivoted on a pin I 46', which inturn is ri i y secured to the selector unit mounting plate I21. Thelower-right end of the lever I41 rests on the upper horizontal sectionof an operating cam trip lever its (Figs. 2 and 10) which is pivoted ona tion therewith is an operating cam hub I54 which in turn has anoperating cam I56 attached to it by screws I55 (Fig. 16). A spacingsleeve I61 (Fig. 15) on the shaft 34 between hubs 45 and I52, assists inkeeping the operating cam I56 properly aligned with its associatedparts. A

collar i56 attached to the shaft 34 by a pin I59 in abutting relation tothe flanged bushing 36 prevents the shaft 34 from moving to the right. A

sleeve me'mber I6I slidably mounted on the sleeve I5! is operativelyconnected to the hub I54 by means of interengaging teeth members I62(Fig. 2). .The sleeve member I6I comprises the driven member of aratchet clutch by means of which the independently rotatable operatingcam I56 is rotated. A spring I63 (Fig. 15) cofled about a sleeve portionof the hub I52 tends to keep teeth I64 disposed on the right face of thesleeve member I6I engaged with similar teeth I65 disposed on the leftface of the gear hub 46. The gear hub 45 comprises the driving member ofthe ratchet clutch, it being attached for rotation therewith to theshaft 34. When the teeth I64 and I65 on the driven and driving membersrespectively are engaged, the operating cam :I66 will rotate with theshaft 84.

A side cam surface I66 (Fig. 2) disposed on a circumference of thedriven member I6I, is in operative relation with the lower end I6! ofthe trip lever I48. With the teeth I64 and I65 (Figs. 2 and 15) engagedand the operating cam I66 rotating with the shaft 34, the side cam.surface I66 is so arranged thatit engages with the and E6! of the triplever I46 at a predetermined point ber to the left and consequently theteeth I64 thereon are disengaged-from the teeth I65 of the drivingmember 46. A further projection of the side cam surface'l66 then engagesthe end I61 of I the trip lever and brings the operating cam as- Isembly to a stop in its predetermined rest position. When the trip leverI46 is tripped as herebefore described, the end I61 thereof and the sidecam surface I66 are disengaged, which allows spring I63 to slide thedrivenmember I6I to the right and cause its teeth I64 to be engaged withteeth I65 of the driving member 45, whereupon the operating cam willrotate with the operating cam shaft 34. Since the cam I26! and theT-lever I41 actuate the trip lever I48 for a short interval of time,the. trip lever'is quickly returned to its normal position by anattached spring I66 (Flg. 10) whereupon end I61 (Fig. 2) rides on thecircumference of the sleeve member I6I in the path of the side cam surfI66. Thus as the operating cam B56 nears thee d or its revolution. the sside cam surface I66 and the trip lever I46 cause the disengagement ofthe ratchet clutch as heretofore described and bring said operating camto a stop in its predetermined rest position. The

shaft 34 is geared to rotate a substantial amount faster than theselector cam shaft 98 and it will therefore complete its revolution andbe stopped in its rest position before the selector cam I23 can actuatethe trip lever I44 to again release the sleeve member I6 I inconjunction with a following ignal code combination.

The operating cam I56 (Fig. 15) is a disc with a portion I69 thereof,shown dotted in Fig. 17, disposed axially toward the left end of themachine. A gathering cam "I and a reset cam I12 attached to the left andright sides respectively of the operating cam disc I56 rotate therewith.These three cams, namely, the operating cam I56, the gathering cam "Iand the reset cam- I12- comprise what will hereinafter be referred to asthe operating cam assembly.

A latch lever I13 (Figs. 16 and 1'7) is pivoted on a shoulder screw I14screwed-into a plate I15 which in turn is secured to a section 39 of themain frame casting. The end of the latch lever I13 is engageable with anedge of the gathering cam I1I when the operating cam assembly is in itsstop position. A spring I16 attached to the latch lever I13 and to a pinI11 in the plate I15 normally keeps the latch lever I13 inoperativerelation with the gathering cam I1I. The purpose of the latch lever isto prevent any rebound or rotationin reverse direction of the operating,

cam assembly that might occur due to its sudden stop by the operatingcam trip lever I46.

The lower ends I16 (Fig. 15) of the selector levers I33 are bifurcatedand are so placed in relation to the operating cam I56 that when theyare in their selected or marking position, the bifurcated ends thereofstraddle the disc of the operating cam I56 as shown by the dottedoutline of a selected selector lever.

A series of flve code disc levers indicated in general at I19 in Fig. 15and individually by reference characters I19a to I19e in Fig. 9 are heldin position by the guide plates I 3|. The

code disc levers I19 rest on spacers I32 (Fig. 15) on the selector unitassembly screws I290 and I29!) and are prevented from moving upward by Aselector lever in its spacing position is not adapted to be operativelyengaged with its associatedcode disc lever. The code disc levers H911 toI19e have adjacent the center thereof projecti0ns'18la to I8Ie as shownin Fig. 9 that extend vertically a predetermined distance and are thenbent to extend horizontally toward the front of the machine. The purposeof these projections will be described in following paragraphs.

Referring to Figs. 15, 16 and 17, as the operating cam assembly startsto rotate, when released as heretofore described, and has completedabout a quarter of a revolution, the gathering cam IH which is attachedto the operating cam I56 and rotating therewith, comes into operativerelation with the-downwardly extending projections I62 on the right endsof the code disc levers I19. Due to theshape of the section I83 of thegatheringcam I11 and its rotating movement, it progressively slides allthe code disc levers I19 that may be in their left position to theirright position. Some or all or none of the code disc levers I19 may bein their left position depending on the previous character selected.Thus all the code disc levers I19 are to the right and in position tohave the selection that is set up in the selector levers I33 transferredto them in a manner that will hereinafter be described. As the operatingcam assembly continues to rotate, the operating cam disc I56 slides inthe bifurcated ends I16 of the selected selector levers I33 and afterabout a half a revolution'of said disc, the displaced portion I69thereof actuates the bifurcated ends of the selected selector leverstoward the left. As the bifurcated ends of the selected selector leversmove to the left, the left sides thereof engage with the right ends oftheir associated code disc levers I19 and consequently slide said codedisc levers to the left into their left position. As will be remembered,the second selector lever I33b, the fourth lever I33d, and the fifthlever I33e, were positioned to their selected or marking position inresponse to received code combination of impulses. Consequently; thesecond, fourth and fifth code disc levers I191), "941, and I19e,respectively, will he slidto the left into their marking position, asthe displaced portion I69 of the operating cam disc I56 actuates theselector code disc levers: The first and third code disc levers H941 andI190 will remain as positioned by the gathering cam I" in their right orspacing position because their associated selector levers I33a and I33cremaining in their normal or spacing position retain their bifurcatedends I16 out of .engagement with the operating cam disc I56.

The code disc levers I19 remain in either their spacing or markingpositions corresponding to the selection transfered to them from theselector levers until the first part of the subsequent revolution of theoperating cam assembly, whereupon all the code disc levers in a markingposition are again moved to their spacing position by the gathering camI1I.

Individual to each code disc lever disc lever detent pawl I64. Thesedetent pawls I64 are pivoted on a common stud I65 attached to theselecting unit mounting plate I21. Individual springs I66 attached to anarm of each detent pawl and to a spring post I81, keep saidpawls'engaged with a wedge-shaped portion I68 of their associated codedisc levers The detent pawls I64 in conjunction with their associatedsprings I66 act as jockeys and tend to keep the code disc levers I19 ineither their marking or spacing position as set by the operatingor-gathering cams respectively.

As the operating cam assembly rotates further, the displacedportion I69of the operating cam disc I56 in passing out of operative relation withthe bifurcated ends of the selected selector levers return said selectorlevers to their right hand position. Further rotation of the operatingcam assembly brings the reset cam I12 into operative relation with thebottom of the selected selector levers and due to the shape of the resetcam and its rotating movement, the selected selector levers are raised.When the'portion I of each of the selector levers is high enough toclear the pivot stud m, attached springs I35 pull the selector leversover onto the stud I42. The reset cam I12 76 I19 is a code.

then passes out from beneath the selector levers and they stay in theirspacing position, as the stud I42 prevents them from returning to theirmarking position. Thus all the selector levers I33 that were actuated totheir marking position by the selector' cams I23 in conjunction with thearmature lever 83 are returned to their spacing or normal unselectedposition and all the selector levers I33'are ready for the nextcharacter code selection. Further rotation of the operating cam assemblyis stopped after one complete revolution as previously explainedby theoperating cam trip lever I48.

' The various functions of the selector cam and of the operating camassembly are so timed that there is no interference in their operation,the selector cam having completed'its selection before the operating camassembly starts to transfer this selection to the code disc levers H9.

Typewheel stop mechanism The typewheel stop assembly, indicated ingeneral by the reference numeral 589 (Figs. 13 and 15), comprises aflanged bearing sleeve 59! surrounding a typewheel shaft sleeve I92, atypewheel shaft I93 and associated parts. The typewheel shaft sleeve I92is attached to the typewheel shaft I93 for rotation therewith by a pinI90. Attached to the bearing sleeve I!" by screws I90, only one of whichis shown in Fig. 13, is a left stop member guide plate I95 and 'a'stopunit mounting plate I96. A clamping washer I91 between the plate I96 anda stop member pivot disc I98 keeps said pivot disc against the leftguide plate I95. Screwed into the right face of the left guide plate I95are a series of four posts I99. On the right side of the flange of thesleeve I9I is a spring plate 2!", a series of spacers 202 and a seriesof filler-washers 200. Supported on each filler-washer are code discsindicated in general at 204 in Fig. 15, and individually by referencecharacters 204a to 2,00 in Fig. 13. The spring plate 2!", spacers 202,and fi1ler-washers 203, are held fast and in position by a right stopmember guide plate 205 attached to the posts I99 by screws 206 in theright ends thereof. As the filler-washers 203 are slightly thicker thanthe code'discs 200, the discs are not clamped tight but are free torotate on the filler-washers 203, being limited in the amount of theirrotation by elongated holes I80 therein, through which pass the postsI99. The code discs 200 are provided with V-shaped notches I60 out alongtheir circumferential edge in a manner well known in the disc 206 hastwo positions.

art.

As will appear from the following, each code For each combination ofsettings of these discs corresponding V- shaped notches I60 on each discwill be in align- At right angles to and code discs and guided in radialslots 201 and 208 in the right and left guide plates 205 and I95respectively, are a series of stop members indicated in general byreference numeral 209. Each stop member 209 is pivotally or otherwisecarried on the periphery of the supporting and pivot disc I98 adjacentthe left end thereof and is provided with a V-shaped edge on the'sectionengageable with the circumferential edges of the code discs 204. Eachstop member has one end of an indiv'idual coil spring -2II attached toit, the other' end of the spring being attached to the spring plate'20l.By the action of these springs. the stop members 20.9 are pulledradially inward and sleeve I9I.

are urged into engagement with the V-shaped notches in the code discs204.

As'stated above, for each setting of the code discs 204 one of the stopmembers 209 will have six of the notches under it in the six discs inalignment and will accordingly be pulled by its attached spring intosaid notches, it being understood by those skilled in the art that thenotches are so cut around the circumference of the discs 204 thatonlyone such alignment of notches can exist at a time. The five codediscs 204a to 2041; are in operative relation with the five code disclevers I'I9ato I'I9e respectively. lilach code disc lever I19 (Fig. 15)is provided on the left end thereof with a downwardly extendingprojection so mounted in relation to the code disc levers I19 that atransverse motion of the'levers imparts a rotary motion to, the codediscs about the bearing The code discs remain 'as positioned by the codedisc levers I19 until the following rotation of the gathering cam I1I(Fig. 17) whereupon all the discs 204 in a marking position are rotated.a few degrees in a clockwise direction (Fig. 15) into a spacingposition by their associated code disc lever acting in conjunction withsaid gathering cam as heretofore described.

With a signaling code composed of five impulses, there are 32 possibleselections and in order to increase .thenumber of possible selectionswithout the addition of another impulse, I

. case shift signals are employed called shift and unshift signals.These two signals by means hereinafter described control the movement ofthe code disc 204i. The notches on the code discs 204a to 204e -aresoarranged that for a predetermined number of combinations of settingstwo rows of notches'therein are in alignment.

Which one of the two stop members 209 associated with the alignednotches will be operated toward the axis of the stop unit is determinedby the position of the code disc 204/, called the shift disc. In oneposition of the shift disc 204] those stop members associated with theunshift signals are selectable and in the other position the stopmembers associated with the shift signals are selectable. The selectionof the shift and unshift signals cause the stop members 209a and 20%respectively (Fig. 14) to' be actuated toward the axis of the stop unit.The disc 204i has no control of the selection of the stop members 209aand 20% as it is cut away beneath these stop members and thereforeeither of these stop members are selectable for either position of theshift disc 20.

Pivotally mounted on a pin 2I5 in the top of the right stop member guideplate 205 is a shift disc lever 2I6. The lower end of the' lever 2I6 is"engage the right side ofthe shift disc lever 2I6. Thespring 2| Iattached to the stop member 209bactuating said stop member causes theshift lever 2| 0. to rotate about its mounting point a few degrees. Theshift lever in turn causes the Shift 26 disc 204i to be rotated a fewdegrees in a counterclockwise direction to a position corresponding toits shift position whereinafter the stop members 209 associated with theshift signal are selectable. With the shift disc in its shift position,a selection of the unshift stop member 2094: will 'cause said disc toreturn to its unshift-position whereinafter the stop members associatedwith the unshift signal are selectable. It will be noted, therefore,that with the shift disc 204! in one position a certain stop member isallowed to be moved toward the center in response to a certain signalcode combination and a different stop member is allowed to be movedtoward the center by the same signal code combination when the shiftdisc is in its other position.

A shift disc detent lever 2|9 (Fig. 15) pivotally mounted on one of thestuds I99 is engageable with a detent roller 22I pivotally mounted on apin 222 in the shift disc 204i. A spring 223, one end of which isattached to the detent lever 2I9 and the other end to a spring clip 224,keeps the end of the lever engaged with the detent roller 22I. ciatedparts is to keep the shift disc in filthGlrOf its actuated positionsduringreception of signals following the shift or unshift signals.

Loosely mounted for independent rotation on the left end of thetypewheel shaft sleeve I92 (Fig. 13) is a flanged gear hub 225. Attachedto the gear hub 225 for rotation therewith by screws. 226 is the gear13. A flanged hub 221 on the left end of the shaft I93 is clamped inabutting relation-to the sleeve I92 for rotation therewith by means of anut 228 in threaded engage- .ment with the left end of the typewheelshaft .I93. On the periphery of th hub 221 .are placed a series ofthreefriction members 229 which are held in place by a circular coiledradially contractable spring 23L Radial slots 233, (Fig. in the frictionmembers 229 engage the three pins 232 carried in the left side face ofthe' gear hub 225 (Fig. 13). The friction members 229 are frictionallyengaged with the peripheries of the hub 221 by the spgpg '23I and tendto rotate said hub therewith. The above described members comprise afriction clutch which is constructed to operatein substantially the samemanner as the hereinbefore described friction clutch on the selector camshaft 98 shown in Figs. and 11.v As heretofore described,-the gear 13(Fig. 5) iscontinually rotating due to the power communicated theretofrom the idler gear 68 and therefore the typewheel shaft I93 will tendto rotate by means of the power communicated thereto through theattached friction clutch.

'Anindex or typewheel stop member 234 (Fig. 13) secured to the typewheelshaft sleeve I93 for rotation therewith, by means of a clamping screw235 therein, rotates in operative relation to the right ends of the stopmembers 209. The stop members are normally out of the path .of the endof the stop arm 234 as it rotates with the typewheel shaft. However,when one of the stop members is positioned in a row of aligned notches,the right end thereof moves into the path of said stop arm 234 andblocks the rotation thereof, thus bringing the typewheel shaft 193 torest in a selected angular position. By selecting various stop members,the typewheel shaft may be selectively stopped at various positions inits rotation. It is to be understood, however, that as'the code discs204 are moved in response to a different 'code'combination' of impulses,the

The purpose of the detent lever and assoselected stop member 209 will becammed out of its selected position into its normal position, the rightend thereof being thus disengaged from the stop arm 234. The stop arm isthen free to rotate with the typewheel shaft until stopped by the stopmember selected by the new positions of the code discs 204 correspondingto the new code combination of impulses. When the typewheel shaft isstopped, the friction members 229 slide on the periphery of the hub 221.

On the right end of the typewheel shaft I93,

. secured by a screw 236, is a flanged typewheel Printing, perforatingand tape feeding mechanisms Clamped to the top right side of the bracket242 by screws 244 is a bushing clamping member 245 which serves to holda flanged bushing 246. Referring to Fig. 10, the right end of anindependently rotatable shaft 241 is journaledin the bushing. 246. Abushing clamping member 248 attached to the section 24 of the main framecasting by screws 249 hold a flanged bushing 251 which serves as anotherjournal for the shaft 241. The shaft 241 and the countershaft 53 are onthe same axis and the shaft 241 is adapted to be independently rotatedfrom said countershaft by means of a hereinafter described ratchetclutch. The ratchet clutch comprises a driving ratchet integral with thehub 49 attached to the shaft 53 and continuously rotating therewith andis keyed to the shaft 241 for rotation therewith but is adapted to beslid along said shaft to bring its teeth 254 into. or out of engagementwith the teeth 253 on the driving member 49. The means by which thedriven member 252 is actuated along the shaft 241 will be describedhereinafter. A circular coiled spring 258 around the sleeve portion ofthe driven member 252 tends to keep the driven member engaged with thedriving member.

A side cam surface 259- (Fig. 12) on the hub portion of the drivenmember 252 is adapted to be operatively engaged with a cam follower 26Ion the lower end of a trip lever 262. The trip lever 262 is pivotallymounted on a stud 263 in the frame section .24. A pin 264 (Figs. 2, 12,16 and 1'1) secured to the hub I54 of the operating cam assemblyis-arranged toengage the upper A member 334 attached adjacent the, leftend of the lever 234 by screws 335'; has pivotally mounted on a pin 336in the left'end thereof a feed pawl 331 best shown in Fig. '7, the upperend of which is adapted to operatively engage the feed ratchet wheel33I. A spring 330 attached to the feed pawl 331 keeps the upper endoperativ'ely engaged with the feed ratchet wheel 33I. An arm 339 pivotedon an eccentric shoulder screw 3 secured to the plate 296, has a detentpin 342 in the right end thereof in operative relation with the starwheel 7 .9. Aretractile spring 343 attached to the arm 339 and a pin 344in the plate 296 holdsthe pin 342 in engagement with the star wheel 329.

The plate 349 (Fig. 6) has a vertically extending portion 354 upon whicha tape retaining finger 356 is pivotally mounted at 355. A- spring, notshown, keeps the tape retaining finger. 356 operatively engaged with thecylindrical portion 332 of the shaft 324. The purpose of the retainingfinger 356 is to keep the pins 333 on the cylinder 332 engaged in thefeed holes in the paper tape.

Referring to Fig. 9, the right ends of the horizontal projections I 8Ia.to I M e of the code disc levers I19 are operatively engaged by springs351 to individual transfer levers 358a to 358e. The transfer levers 358ato 358e are individually bent and shaped, being pivoted adjacent thecenter thereof on a common shoulder screw 359 horizontally secured tothe section 24 of the main frame casting. Secured by screws 36I to-theeach transfer lever is rounded and is engaged by the right bifurcatedend of its associated sliding bar 293. i

The operation of the printing, perforating and tape feeding mechanismswill now be described in conjunction with the operation of the selectormechanism. As is evident from Figs. 6 and 9, transverse movements of thecode -disc levers I19 will rock the transfer levers 359 about theirpivot mounting point. As was heretofore described, the gathering cam I1I(Figs. 16 and 17) during the first part of the revolution of theoperating cam assembly positioned all the code disc levers to theirspacing position, thus rendering them adapted to receive the selectionset up in the selector levers I33. As any of the code disc levers I19were moved to the spacing position, its attached transfer lever 353(Figs. 6 and 9) will be rocked in a clockwise direction whereupon itsassociated sliding bar 293 will be slid to the left into its spacingposition. Thus all the sliding bars 293 will be in their spacingposition which renders the left vertical section 366 thereofunengageable with the lower end of their associated punch pin 304. Asthe second, fourth and fifth code disc levers I191), I191! and I19e, inthe example heretofore assumed, are moved totheir marking position bythe operating cam I56 and associated selector .levers I33, the transferlevers 358a, 35807 and 3586' will be rocked in a counterv Near the endof the revolution of the operating cam assembly the pin 264 (Fig. 12)actuates the trip lever 262 to initiate the rotation of the shaft 241with the countershaft 53.

therewith. After having completed about ahalf a revolution, the low partof the print cam 216 (Fig. 6) is operatively engaged with itsassociated.

.the typewheel, which is dampened with ink by means hereinafterdescribed, will take an impression therefrom. The typewheel wasselectively stopped in a position that would bring the charactercorresponding to the received code combination of impulses intooperative relation with the projection 322 on the print lever as washereinbefore described; The shaft 241 in rotating about a half arevolution from its rest position also brings a high part of the cam 211into operative relation with its associated cam follower 236 andconsequently causes the lever 284 to be rocked in clockwise directionabout'its pivot mounting point. This brings the vertical sections 366 ofthe sliding bars 293 in a marking position in contact with the bottom oftheir associated punch pins 304 and forces the pins upward, causing theupper ends thereof to punch holes in the paper tape P. As the lever 284rocks in a clockwise di rection, the plate 294 engages the bottom of thefeed hole punch pin 341 and causes a feed hole to be punched in thetape. The left end of the lever 284 in rising also allows the pawl 331(Fig. '7) to rise and engage a higher tooth on the feed ratchet wheel33I, and as the lever is returned to its normal position by the spring3I8, as the cam 211 approaches its rest position, the feed ratchet wheelwill be. stepped an amount equal to one tooth on said ratchet wheel. Theratchet wheel 33I in stepping one step causes the paper tape P to beadvanced a distance equal to one letter space by means of the pins 333in the enlarged cylindrical portion 332 of the shaft 324 engaging feedholes in the tape. This presents a fresh surface in the paper tape P tobe in operative relation with the typewheel 239, the feed hole. punchpin 341 and the punch pins 304. The pin 342 on the arm 339 engaging thestar wheel 329, keeps theshaft 324 and attached members in positionafter being stepped. The lever 234 in returning to its normal positionalso allows the springs 346 and 352 on the punch pins 304a, 304d and 341to return the actuated pins to their normal lower position. The feedpawl 331 is adapted to rotate the feed ratchet wheel 33I after the punchpins 304 and 341 are disengagedfrom the paper tape.

From the above paragraphs it is evident that on every revolution of theshaft 241 a. feed hole will be punched in the tape and the tape advancedone letter space.- It is also evident that the pins 304 will punch acombination of holes in the tape that will represent the selectedcharacters and that the print lever 3I5 will be actuated to cause theimpression on the typewheel representing the selected character to berecorded on the paper tape.

Referring to Figs. 4 and 6, the feed holes 361 The print and perforatingcams 216 and 211 (Figs. 6 and 10) being attached to the shaft 244, willrotate,

are punched by the feed hole punch pin 341. The holes 363a to 366a arepunched by their associated I3 315. The tape container 315 (Fig. 2) isadapted 2,174,781 punch pins 3040. to 304e and the character prints .intwo forms. The imprint of the typewheel represents the character in aprinted form and the combinations of holes represent the combinations of.impulses in a perforated form. In the preferred embodiment of theinvention the printing and perforating operations for a character areadapted to be recorded and register on the same transverse section oftape. The selection of a character composed of the following impulses,spacing; marking, spacing, marking, and marking, was described and sucha character will be registered on the tape by the transverse sectionsindicated by the reference numeral 31! (Fig. 4).

Referring to Fig. 5, a bracket 312 attached to the base plate 2!. byscrews 313, has-attached to its upper end by screws 314 a tape containerto hold a roll of tape 316 and allow it to be freely unrolled as it isfed through the machine. A roller 311 pivotally mounted on a shoulderscrew 318 attached to the section 24, of the main frame assists inguiding the tape P through the ma-' chine.

A typewellinking means comprising an absorbent ink roller 319 (Fig. 2)an intermediate roller 38!, and a container 382 for the rollers 319 and38l is supported by an arm 385 which is attached to the main framesection 24 by screws 383. The rollers 319 and 38l are pivotally carriedby the container 382 and the circumference of the intermediateroller 38lis in contact with the circumference of the typewheel 239 and with thecircumference of the ink roller 319. Thus the circumference of thetypewheel is dampened with ink as the typewheel rotates.

Two spring clips 386 and 381 (Figs. 2 and 3), are attached to themachine by the mounting screws I 303 and 22, respectively. These clipsholda container 388 adapted to receive the tape punchings. Two hollowmembers 389 and,39l attached to the top of the plates 309 and 351respectively, (Fig. 6) by 'the plate mounting screws, are adapted toguide the tape punchings into the container 388 as they are forced fromthe plates 309 and 35L 4 A spring arm. 392 (Fig. 6) attached to theplate 296 by the mounting screw 291 has the upper end thereof engagedwith the typewheel shaft I93. The am 392. assists in steadying thetypewheel shaft as it rotates.

In some of the views the ink rollers container 382 andthe tape punchingscontainer 388 are not shown in order to more clearly show some of theother essential parts.

While this invention has been shown in but one form, it will be obviousto those skilled in the art that it is not so limited but is susceptibleto various changes and modifications without departing from the spiritor essential attributes thereof, and it is desired, therefore, that onlysuch limitations shall be placed thereon as are imposed by the prior artor are specifically set forth in the appended claims. 7
